Zylinderschloss.

摘要

The cylinder lock has a pair of coaxial bushes (23a, 23b), accommodated in seats (20) provided with external teeth (24a, 24b). The bushes are rotationally coupled to plugs (5a,5b) and slide axially to engage an opening (18) of the bit (14) to define a rotary coupling therewith. A tube (33) is arranged coaxially in said bushes (23a, 23b), a pair of mushroom-shaped elements (29a, 29b) whose stems (30a, 30b) are guided in the opposite ends of said tube (33) and whose circular plates (31a, 31b) are guided in said bushes, said bushes having, in their adjacent ends, internal rings slideable on said tube and, in their opposite ends, diametrical notches and internal collars (27a, 27b) for the abutment of said circular plates (31a, 31b), a spring (32a, 32b) being arranged in each bush, said spring acting between each ring and the related circular plate (31a, 31b), a further spring (34) being arranged inside said tube (33) and acting between the mushroom-like elements (29a, 29b), shoulders being provided on the tube for the abutment of said rings which stop said bushes (23a, 23b) at a distance that at least one of them is rotationally coupled in the opening (18) of the bit.
